摘要
本文选取细度不同的两种硅灰石样品,分别采用两种不同的加工工艺进行粉碎。通过一系列测试手段对比研究可以发现,粉碎前经煅烧处理的硅灰石长径比大于直接进行粉碎的硅灰石长径比; 加工前样品的细度越小,煅烧处理后粉碎所得硅灰石长径比越大,因此硅灰石粉碎之前预先进行煅烧空冷处理不失为一种保护其长径比的好方法。
After choosing two kinds of wollasonite samples which have different particle size, crushingthem in different processing methods. By means of a series of measuring approach we can reveal that the ratioof length to diameter of the wollasonite which is calclined before crushing is higher than that of thewollasonite which is crushed immediately .The smaller the particle size of original wollasonite sample, thebigger is the ratio of length to diameter of the last product. So calclining wollasonite before it is crushed isa good method for protecting the ratio of length to diameter.
